Derivative - Wikipedia
en.wikipedia.org › wiki › DerivativeHere ∂ is a rounded d called the partial derivative symbol. To distinguish it from the letter d, ∂ is sometimes pronounced "der", "del", or "partial" instead of "dee". In general, the partial derivative of a function f(x 1, …, x n) in the direction x i at the point (a 1, ..., a n) is defined to be:

Notation for differentiation - Wikipedia
en.wikipedia.org › wiki › Notation_for_differentiationThe symbol () is the derivative of the temperature T with respect to the volume V while keeping constant the entropy (subscript) S, while () is the derivative of the temperature with respect to the volume while keeping constant the pressure P. This becomes necessary in situations where the number of variables exceeds the degrees of freedom, so that one has to choose which other variables are to be kept fixed.
Derivative - Wikipedia
https://en.wikipedia.org/wiki/DerivativeDifferentiation is the action of computing a derivative. The derivative of a function y = f(x) of a variable x is a measure of the rate at which the value y of the function changes with respect to the change of the variable x. It is called the derivative of f with respect to x. If x and y are real numbers, and if the graph of f is plotted against x, derivative is the slope of this graph at each point.
